Integrated pressure reducing valve having a single fitting for fluid inlet and outlet

摘要

Valve comprises a body (1) with a fitting (30) to the bottle with a first channel (19) to the bottle and a single coupling (2) with a second channel (11) through which fluid enters or exits. First and second channels are connected via a third internal channel (16) within a low-pressure chamber (14) and associated valve gear (31-37) for fixing either an inlet or outlet path.
